GEORGE ROSQUIST, OF BROOKLYN, NEW YORK.

WEB-WlNDlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 232,650, dated September 28, 1880,

Application filed January 2, 1880.

To all whom it may concern:

'Be it known that I, GEORGE ROSQUIST, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Web-Winding Machines, of which the following is a specification.

My invention has for its object to provide an imPI'OXBd mechanical device for use in papeer and cotton mills, wall-paper manufactories, newspaper press-rooms, and other establishments where it is necessary or desirable to maintain uniform and invariable surface speed of an endless web of paper or other material while it is being wound onto a spindle, or, in other words, to decrease the speed of the revolving shaft or spindle upon which the web is being wound in exact proportion as the diameter of the roll increases by added coils of the Web, and to maintain rotundity of the roll and uniform compactness and. tension of the web as the size of the roll is enlarged or diminished in winding onto or off from a revolving spindle.

Probably the best method hitherto known for maintaining even surface speed of an increasing web-roll is that applied to wettingmachines, or such as are used for uniformly dampeninglong Webs of printing-paper for rotary newspaperpresses. In these machines the motion is imparted to the web-roll by friction from the surface of a revolving cylinder. This is liable to the objection that the motor-cylinder, in order to revolve the paperroll, is constantly. dragging the surface-coil of the latter in the direction of the motion, thereby causing the paper to Wrinkle andfrequently break. The compactness and rotundity of the roll are constantly decreased by added welts of compressed puckers as its diameter increases, and when again unwound on the press to receive the impression from the revolving stereotype-plates repeated breakages of the paper occur, causing waste of time and material, while the wrinkles in the paper blurr the clearness and legibility of the impression.

My invention obviates said objections.

In the accompanying drawings, Figure 1 represents an end elevation, partly in section, on the line 2 zof Fig. 3, of a paper-wetting machine embodying my present invention. Fig. 2 is a top view of the same, showing the operating mechanism with the winding devices omitted. Fig. 3 is a vertical section of the same, taken through the line a: a: of Fig. 2, and seen in direction of arrow 1. Fig. 4 is a detail cross-section through the lineyy of Fig. 3, seen in direction of arrow 2. 5 is a sectional detail.

Similar letters of reference indicate like parts in the different figures.

I11 this invention the frictional motor-cylinder is dispensed with and power applied directly to the spindle or spool on which the web is being wound. The web-roll, as it revolves and increases in size from the winding of the material upon its outer surface, is made to actuate a feed, which gradually, as the material is wound upon the surface of the web-roll, decreases the velocity of its spindle, so as to give a uniform surface motion to the web. The web is wound upon a round wooden spool, having a square axial hole to fit upon a square spindle hating journals turned upon its ends, so that the spool and spindle shall revolve together.

The dry roll of paper to be dampened is placed upon the spindle A, which has a smoothfaced end pulley, a, revolving in'a stationary friction-clamp, a, adjustable by a screw, z, and nuta in the usual manner. The web unwinds from the spindle A in the direction of arrow 3, and is wound upon the spindle B by the revolution of the latter, and is acted upon during its passage by a fine downward-pointing spray of water (not shown in the drawings) arranged above the web between the two spindles.

The spindle B revolves in U-shaped end bearings, 0, so that it may be easily inserted and removed and is held is place during its revolution by cross-pins c or other suitable device.

The bearings c and all other necessary bearin gs of this machine are attached to any suitable frame-work O, the construction of which may, of course, be varied to adapt it to its several uses.

When the wiudingspool b has been pushed on the spindle B the latter, in being placed in the bearings 0, is simultaneously inserted with one end, I), (which is flattened for the purpose,) in a suitable clutch, D, so as to rethe end of a shaft mounted in bearings 01, in axial line with the spindle B, and upon the said shaft is mounted a pulley, E, receiving motion by a belt, 6, from a pulley, F, secured upon a counter-shaft, f, which latter works in bearings g and runs parallel with the spindle B.

The shaft f is made square for a sufficient length atf, and upon the square portion is fitted to slide the hub h of a thin smooth-faced wheel, H, so that the wheel H must revolve with the shaftf, and yet can be slid longitudinally upon the shaft f. The same result may be accomplished by fitting the hub h to slide upon a spline or groove in the shaftf instead of upon the square f.

The wheel H is revolved by friction from the surfaces of two circular disks, I, turning in opposite directions in contact with diametrically-opposite points of the face of the wheel H. The hubs z" of the disks 1 are mounted to turn upon a stationary shaft, K, whose axis is arranged at right angles to and intersects the extended axis of the shaft f.

Upon the hubs t of the disks 1 are formed or attached pulleys J, which receive the motion necessary to revolve the disks I by belts j j from pulleys L, secured upon the main shaft M, to which latter motion is imparted from the engine by a belt over pulley N. In order to cause the disks 1 to turn in opposite directions, one of the helts,j, is crossed between the pulleys L J.

It is evident that the wheel H may be revolved by only one of the disks I; but the use of two, as shown, is by far more preferable, since it gives more friction with the same power and neutralizes the efi'ect of the lateral pressure upon the shaft f.

The amount of friction and gradual loss by wear of the surfacesin contact are regulated and compensated for by spiral or other springs,

70, arranged upon the shaft K to press endwise upon the hubs 15 toward the center of the wheel H, the tension of the springs being adjusted by nuts or sliding collars k, securable in the adjusted positions upon the shaft by setscrews k It is evident that the shorter the friction radius-or, in other words, the nearer to the center of the shaft K the wheel H slides while in contact with the disks I-the slower will be the motion of the spindle B, and vice versa. To maintain a uniform surface speed of the winding web, it is thus only necessary to slide the wheel H toward the shaft K in the same The other ends of the levers P are pivoted at p to the ends of a bail, R, which is connccted at its middle to one end of a connecting-rod, S, whose other end is pivoted at s to one end of a bell-crank lever, T, fulcrumed above the shaft f, at g, to lugs on a bracket, Gr, attached to the frame-work O. The other end of the bell-crank lever T is forked astride the hub h of the wheel H, and provided with pins 1., entering on opposite sides a groove, 71., turned in the hub h, whereby the latter is reciprocated on the shaft f when the lever T is oscillated upon its fulcrum g. Thus for every coil of paper increasing the size of the roll on the spool 12, the roller Q is pressed outward from the center of the spool a distance equal to the thickness of the paper, and, by means of the levers P, bail R, connecting-rod S, and lever T, actuates the hub h, sliding the wheel H nearer to the center shaft, K, thereby decreasing the speed of the spindle B proportionately as the paper-rollincreases in diameter.

In order to adjust the position of the wheel H on the shaft f to obtain a greater or less surface speed to suit a web of different material, the bail R and rod S are connected together by a screw, U, swiveled through the bail and screwing into a threaded socket in the rod S, as shown in Fig. 5. The screw U has a handwheel, a, for operating it, and when adjusted to secure the proper distance between the bail R and the pivot s it is kept from accidental turning by the jam-nut u tightening against the end of the rod S. The

swiveled end is kept in proper position in the -screw it upon the shank of the screw U.

In order to form a uniformly-compact rollit is also necessary to apply uniform tension. I have therefore provided the following means for accurately measuring the degree of tension in pounds of pressure: The web, in traveling between the spindlesA and B, is made to pass over a roller, V, pivoted between two vertical standards, W, each of which is sliding in a hole in an arm, X, attached to the standard 0, and with its lower end in a socket, Y, in the frame O. A spiral spring, Z, upon the rod 0, expanding between the frame 0 and a shoulder, 3 tends to raise the roller V against the downward pressure caused by the tension of the web.

The standard W is graduated with lines distanced apart according to pounds of compression of the spring Z, and the pressure is read in a small opening, 00, in the arm X by the juxtaposition of one or other of the divisionlines on the scale to a stationary index, 02 or the scale may be read at the upper or lower edge of the arm X. By the assistance of this gage the clamp on may thus be adjusted to give the same tension to the webs of any number of rolls consecutively operated upon.

Having thus described my invention, I claim as new and desire to secure by Letters Pat ent- IIO 1.
